Well that even makes things even further confusing. You got a "supposed" message from a developer that says
Run block rating = Only sim engine uses
Pass block rating = Only sim engine uses
RBF, RBS, PBF, PBS = Only IN-Game uses
If that is the case, how many people look at a high run block rating and pass block rating and think their guy is good at blocking based on this rating which means NOTHING for them in game.
This further proves we need some insight into what ratings do what, why, and how. Also WHY would they even have ratings for "sim" engine only, yet have nothing to signify that??
I am not calling you a liar or anything. Maybe this message really exists from a developer but what I am saying is this is all very confusing about what does what, what ratings battle other ratings, what is sim engine ratings, what is in game ratings, and on and on and on!!!
